ADDITIONAL SYSTEM INFORMATION :
I'm running System 76's Pop-OS 18.10 (which is based on Ubuntu) on a 64-bit machine.
The java version (as reported by java -version) is:
openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment (build 11.0.1+13-Ubuntu-2ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.1+13-Ubuntu-2ubuntu1, mixed mode, sharing)


A DESCRIPTION OF THE PROBLEM :
The manual page for the java command do not mention options such as he classpath, module-patth, add-modules, etc. It refers to a section named "Setting the Class Path "
[with a blank before the quote as shown] but that section does not seem to exist.

A previous bug mentioned missing classpath documentation, but claimed that this was fixed in Java 9 and above, but it seems to be in Java 11, so I presume it somehow showed up again (possibly someone updating the documentation started with a file in which these options were missing).

REGRESSION : Last worked in version 11.0.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
type "man java" into a terminal

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
An accurate man page.
ACTUAL -
A man page with options missing.

FREQUENCY : always
